|
|

|
|
* eliminates the need for glue files: npunix.c, npwin.cpp and npmac.cpp that
|
|
* get linked with the plugin. You will however need to link with the "backward
|
|
* adapter" (badapter.cpp) in order to allow your plugin to run in pre-5.0
|
|
* browsers.
|
|
*
|
|
* <P>See nsPlugin.idl for an overview of how this interface fits with the

|

|
|
* displaying another plugin manager window, causing the page containing
|
|
* the plugin to become removed from the display).
|
|
*
|
|
* Destroy -- called once, before the plugin instance peer is to be
|
|
* destroyed. This method is used to destroy the plugin instance.
